In the Bible, there are a set of books that contain the letters from Paul. Paul was an apostle of Jesus. He wrote these letters at different times during his life. These letters became a part of the Bible in certain parts of the Bible. This part is called the Pauline Epistles. The books of the Bible that are written as part of the Pauline Epistles and contain the letters from Paul are Ephesians, First Timothy, Second Timothy, and Titus.
James is not part of the books. Several other books of the Bible contain these letters, and these include Romans, First Corinthians, Second Corinthians, Ephesians, Philippians, Colossians, First Thessalonians, Second Thessalonians, Hebrews, and Philemon. All of these books are in the New Testament.
